I hate to add to everyone else, but I also agree with them. At the VERY least, get a separation. If he does go out on another binge, YOU are protected. While he is in recovery, you need to be focused on you. Regardless of what he is saying now, hasn't he said it before? Haven't you heard over and over how he's done and "give me another chance...I'm serious this time"??? My ABF has been serious so many times I can't even count.
Protect yourself, protect your children. Let him continue his recovery. Like Cynical said, if he is serious, and wants real recovery, then in a few years you can consider getting back into a relationship or marriage again - but ONLY after he has proven this track.
